下载163的源，这是centos7的

# curl -o CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo

其余的源地址

CentOS5 ：http://mirrors.163.com/.help/CentOS5-Base-163.repo
CentOS6 ：http://mirrors.163.com/.help/CentOS6-Base-163.repo

新加密方式 caching_sha2_password
ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
就加密方式 mysql_native_password
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
#添加远程登陆用户
CREATE USER 'ycx'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'ycx'@'%';
